To all whom it ma concern.'V

Be it known t at I, EDWIN GEDOKE, a subject of the King of Great Britain, residing at` Kindersle in the Province of Saskatchewan and ominion of Canada, have invented new and useful Imfprovements in Plowsha'res, of which the ollowing is a specification.

The invention relates to plows and 1t has particular reference to an improved method of attachin' the share to the mold` board and land'si e of an ordina? plow.

The customary metbo of attaching shares is by means of bolts or rivets. When shares are to be detached for sharpening or other urposes rivets are manifestly objectionab e, while bolts are liable to become rusted, thereby making the detachment of the nuts diicult. The object of the present invention stherefore to devise a novel and improved method 'of attachin the share whereby the objections hereto ore existing will be entirel overcome.

A further o ject of the invention is to so connect. the `share `with the mold boa-rd and land side of a plow that it may be instantly detached withoutthe use of tools of any kind.

A further object of the invention is to devise a method of mounting sharesby which the use of bolts, rivets or other like permanent lfastening means will be avoided.

With these and other objects in view, the invention consists in the improved construction, arran ement and combination of parts which wil be hereinafter fully described and particularly pointed out in the claims.

In the drawings hereto annexed has been illustrated a sim le and preferred form of the invention; it ing, however, understood that no limitation is necessarily made to the recise structural details therein exhibited,

' ut that' changes, alterations'andmodilications within the scope of the ap ded claim may be resorted to whendesi In the drawing Figure 1 is a top 1an view of a portion of e invention. lan view of the same.

Fi 6 is a detail side view of a ortion of the p ow as seen from the land si e. Correspondin parts in the several figures are denoted b l1 e characters of reference.

The mold oard a ortion of which is shown at 15, is oi ordinary construction, sald mold board bein connected with the land slde, a portion o which appears at 16. Permanently secured on the inner face of the land side is a connecting plate 1T which'in ypractice-lies adjacent to the inner face of 'the land side member 18 associated with the v'share 19 which latter, as will be seen, is of ordinary contour and general construction. The land side .member 18 is provided with one or more pins or pegs 2O projecting inwardly so as to engage corresponding apertures or perforations. 21 in that portion of the connecting plate'l'( which lies adjacent to the land side member 18. The mold board 15 is rovided on its under side with an arcuate ug or projection 22 which is fixedly attached thereto and which (projects by simply placing the lpins in engagement' with the' apertures 21 and at the same-time iding-the lug or projection 22 into the eeper 23. Owlng to the arcuate shape of the lug it will, by engagement with the wall of the keeper, be ressed in .the direction 4of the land side mem er 18 while it is being in-` serted into the keeper, thereby'causin the pins or pegs exten ing from said lan side member to .enter the a ertures 21. When the lug or projection 22 as been ressed home in the keeper the parts will be ound tofhave been practically assembled for working purposes, it being obvious that the. strain exerted bythe soil against the share when' the plow 1s in o eration will tend to increase the secur/it ofe connection. On the other hand, to ble the partait is only necessary to take hold of the 13% of the share and to ull the latter forw' y when am entre wai' become readily detached.

' Hav' thus described the invention what is claime is:-

A plow bottom comprising a mold board having a 1permanent landside member', a oouillng p ate secured vto the inner face of sal landside member and extending forwardly with respect thereto, said coupling' plate having several apertures, an' arcuate lug fixed on the underface of the mold board and projecting forwardly therefrom, and a share having a keeper to receive said arcuatelug, said share having also a landside member provided with plnsthat are curved in i,asapoe diraeol of' ue impar .waichaivw eareua ug su pmsengw ging a r- 16 tures in the cbuplin plate -on whichpthe landside member of e share abuts in alinement with the landside member of the mold board.

In testimon whereof I aix my signature 20 in preseneeo two witnesses.
